Double blind study definition6/24/2023 ![]() An excellent clinical protocol may help ensure that within the ethical and practical constraints, blinding is achieved as effectively as possible. For example, the method of drug delivery may not be amenable to blinding. Unfortunately, blinding is not possible to achieve in all clinical trials. This type of clinical study ranks as the gold standard for the validation of treatment interventions. Neither the researchers nor the study subjects know who is getting the experimental treatment and who is getting a placebo. Triple-blinding involves withholding this information from the patients, researchers, as well as data analysts.Randomized, double-blind placebo-controlled trials involve the random placement of participants into two groups an experimental group that receives the investigational treatment and a control group that acquires a placebo. A double-blind study blinds both the subjects as well as the researchers to the treatment allocation. A single-blind study masks the subjects from knowing which study treatment, if any, they are receiving. Single-, double-, and triple-blinding are commonly used blinding strategies in clinical research. Issues of Concernīlinding covers any of the numerous participants of the clinical trial, e.g., researchers, subjects, technicians, and data analysts. ![]() It is an essential methodological feature of clinical studies that help maximize the validity of the research results. īlinding or masking refers to the withholding of information regarding treatment allocation from one or more participants in a clinical research study. ![]() A clinical research study or a clinical trial is an experiment or observation performed on human subjects to generate data on the safety and efficacy of various biomedical and behavioral interventions.
